Key Parameters

Substitute Part Grouping Explanation

Substitute parts RS07K-GS08 and RS07K-GS18 are functionally equivalent to the HS1KL RTG based on the following critical parameters:

Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 800 V
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Differing Parameters:

• Current - Average Rectified (Io): Substitute parts rated at 500 mA versus main part at 1 A
• Voltage - Forward (Vf) (Max) @ If: Substitute parts at 1.3 V versus main part at 1.7 V
• Reverse Recovery Time (trr): Substitute parts at 300 ns versus main part at 75 ns
• Current - Reverse Leakage @ Vr: Substitute parts at 2 µA versus main part at 5 µA
• Packaging Format: RS07K-GS08 supplied in Cut Tape (CT) & Digi-Reel®; RS07K-GS18 supplied in Tape & Reel (TR)

The substitute parts are rated for lower average rectified current (500 mA) and exhibit different reverse recovery characteristics. Selection between these parts depends on circuit current requirements and application-specific performance criteria.

Parameter Comparison

Engineering Selection Recommendations

HS1KL RTG Selection Criteria: The HS1KL RTG is appropriate for applications requiring 1 A average rectified current capacity with 800 V reverse voltage rating. This part is Active status with ROHS3 compliance and unlimited moisture sensitivity. The 75 ns reverse recovery time supports fast switching applications. Inventory availability is 938 pieces.

RS07K-GS08 Selection Criteria: The RS07K-GS08 is suitable for applications with maximum 500 mA average rectified current requirements at 800 V reverse voltage. This part carries Automotive grade classification with AEC-Q101 qualification, indicating suitability for automotive applications. Packaging is supplied in Cut Tape (CT) & Digi-Reel® format. Inventory availability is 50,300 pieces. The 300 ns reverse recovery time is appropriate for standard switching applications.

RS07K-GS18 Selection Criteria: The RS07K-GS18 is functionally identical to RS07K-GS08 with the same electrical specifications and Automotive grade with AEC-Q101 qualification. The primary distinction is packaging format supplied in Tape & Reel (TR). Inventory availability is 50,802 pieces. Selection between RS07K-GS08 and RS07K-GS18 depends on assembly line equipment compatibility and tape format requirements.

Substitution Constraints: Substitute parts RS07K-GS08 and RS07K-GS18 are rated for 500 mA average rectified current, which is 50% of the HS1KL RTG rating. These substitutes are not suitable for applications requiring the full 1 A current capacity of the main part. The 300 ns reverse recovery time of substitute parts is longer than the 75 ns specification of the main part, affecting switching speed performance in high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can RS07K-GS08 or RS07K-GS18 directly replace HS1KL RTG in all applications?

A: No. The substitute parts are rated for 500 mA average rectified current compared to the HS1KL RTG at 1 A. Direct substitution is only valid for circuits designed for maximum 500 mA operation. Applications requiring the full 1 A capacity must use the HS1KL RTG or equivalent 1 A rated parts.

Q: What is the difference between RS07K-GS08 and RS07K-GS18?

A: Both parts have identical electrical specifications and Automotive grade with AEC-Q101 qualification. The difference is packaging format: RS07K-GS08 is supplied in Cut Tape (CT) & Digi-Reel® format, while RS07K-GS18 is supplied in Tape & Reel (TR) format. Selection depends on assembly equipment compatibility.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the DO-219AB package with Surface Mount mounting type, ensuring mechanical and footprint compatibility on PCB designs.

Q: What does the 75 ns versus 300 ns reverse recovery time difference mean?

A: The HS1KL RTG has a 75 ns reverse recovery time, enabling faster switching transitions. The substitute parts at 300 ns have slower recovery characteristics. In high-frequency switching applications, this difference affects circuit performance and efficiency. Applications with strict switching speed requirements must use the HS1KL RTG.

Q: Are the substitute parts suitable for automotive applications?

A: Yes. RS07K-GS08 and RS07K-GS18 carry Automotive grade classification with AEC-Q101 qualification. The HS1KL RTG does not specify automotive qualification in the provided parameters.

Q: What is the significance of the forward voltage difference (1.7 V versus 1.3 V)?

A: The HS1KL RTG has a maximum forward voltage of 1.7 V at 1 A, while substitute parts specify 1.3 V at 1 A. Lower forward voltage in substitute parts results in reduced power dissipation. However, this parameter is measured at different current levels (1 A for both), so direct comparison requires circuit-specific analysis.

Q: Can I use these parts interchangeably based on voltage rating alone?

A: No. While all three parts share the same 800 V reverse voltage rating and DO-219AB package, current rating differences are critical. The HS1KL RTG at 1 A and substitute parts at 500 mA represent different current handling capabilities. Selection must account for actual circuit current requirements.
